Micro Surface TensioMeter

The micro surface Tensiometer analyzes wettability by measuring the surface or interfacial tension of liquids, based on the principle of detecting the deformation of tiny droplets or bubbles through mechanical or optical methods. It is used in industries such as coatings and inks to evaluate the spreading and adhesion properties of materials, and in research and development as well as quality control to detect the surface characteristics of liquids such as solvents and resins.
Selection
When selecting a micro surface tension meter, it is essential to consider that the measurement range covers the surface tension values of the liquids to be tested, the accuracy meets application requirements, sample compatibility adapts to different chemical properties, ease of operation ensures daily use efficiency, and maintenance costs and equipment durability match laboratory conditions.

Surface Tensiometer Evaluates the Wetting and Spreading Properties of Resin Liquids
This article introduces how to use a surface tensiometer to evaluate the wetting and spreading performance of resin liquids. Wetting and spreading affect the adhesion and appearance of products such as coatings and adhesives, and the process can be described by Young's equation and the spreading coefficient.
Determination of Static Surface Tension of Color Coatings Using the Platinum Plate Method with a Surface Tensiometer
This article introduces the method of measuring the static surface tension of colored paints using the platinum plate method. It explains the principle, which involves calculating the surface tension by measuring the force when the platinum plate is lifted from the liquid surface.
Surface Tensiometer: Interpreting the Invisible Forces on Liquid Surfaces
Surface tension is the contractile force generated by the uneven forces acting on molecules at the liquid surface, influencing phenomena such as droplet formation and capillarity. Surface tension meters measure this force using techniques like the Wilhelmy plate method, the platinum ring method, or the pendant drop method. Their core components include force sensors, sample stages, and data processing systems.
Surface Tensiometer vs. Contact Angle Goniometer: Which One to Choose for Wetting Studies?
Surface tension meters primarily measure the surface tension of liquids and are suitable for analyzing the properties of liquids themselves, such as purity or the effects of additives. Contact angle meters, on the other hand, evaluate the wettability of solids by analyzing the contour of liquid droplets on solid surfaces, and are commonly used in surface treatment or coating research.
Tips for Cleaning and Maintaining the Platinum Plate/Ring of a Surface Tensiometer
In the field of laboratory testing, the measurement accuracy of a surface tensiometer largely depends on the cleanliness and intact condition of its key components—the platinum plate or platinum ring. This article explains how to maintain them.
How does a surface tensiometer determine the success or failure of printing quality?
